How Do I Calculate My True Home Equity Before Buying and Selling in Calgary in 2026?
Your true net equity is your home's estimated sale price minus your mortgage balance, minus all selling costs, including realtor commissions (typically 7% on the first $100,000 and 3% on the remaining balance), legal fees (around $2,000), and preparation costs like painting or staging ($4,000-$8,000). This real number is usually $30,000-$50,000 less than most homeowners calculate.
Most Calgary families upgrading their homes make the same expensive mistake. They calculate their equity as simply their home value minus mortgage balance, not realizing this fantasy number can cost them tens of thousands of dollars when they actually try to move.
After 20 years of helping Calgary families navigate home upgrades, the math families do at their kitchen tables is almost always wrong. It's not because you're bad at math. It's because there are hidden costs that no one talks about until it's too late.
When you sell a $600,000 home with a $400,000 mortgage balance, most people think they have $200,000 in equity. Here's what that $200,000 actually becomes after real selling costs:
- Realtor commissions: $22,000 (7% on first $100,000, then 3% on remaining $500,000)
- Legal fees: $2,000
- Preparation costs: $8,000 (painting, staging, repairs you've been putting off)
- Your true net equity: $168,000
You just lost over $30,000 that you thought you had. This isn't ghost money anymore. This is your actual down payment for your next home.

How Do I Calculate the Gap Between My Equity and My New Home Down Payment?
The gap is the difference between your true net equity and what you actually need to close on your upgraded home. For an $850,000 home purchase with your $168,000 in true equity, here's what happens:
- Down payment needed (20%): $170,000
- Your true equity: $168,000
- Shortfall on down payment: $2,000
- Closing costs on purchase: $10,000 (inspections, legal fees, moving costs, property tax adjustments)
- Total cash needed to close: $180,000
- Your gap: $12,000
Knowing this $12,000 gap before you start house hunting changes everything. You're not looking at $950,000 houses anymore. You're looking at $850,000 houses, or you need to plan for that additional $12,000 from savings or a line of credit.
What Does It Cost to Own Two Homes at Once in Calgary?
If you buy before selling, you'll carry two properties simultaneously. Here's what 30 days of double ownership actually costs:
- Current home carrying costs: $3,500/month (mortgage, taxes, utilities, insurance)
- Bridge financing on new purchase: $6,000/month (prime plus 2%, admin fees)
- Total monthly cost: $9,465
If your current home takes 60 days to sell, you're looking at nearly $19,000 in carrying costs. At 90 days, that jumps to over $28,000.
Before you commit to buying first, stress test this. Can you comfortably afford 90 days of these double payments without touching your emergency fund? If the answer is no, you cannot afford to buy first.
What Is My Walkaway Number and Why Does It Matter?
Your walkaway number is the absolute minimum sale price you need on your current home to make the upgrade math work without destroying your savings. Using our example:
- Total obligations: $621,000 (mortgage payoff, selling costs, down payment, closing costs, bridge costs)
- Current estimated sale price: $600,000
- You're short: $21,000
This means any offer below $621,000 requires you to add money from your own pocket. Any offer above $621,000 puts money in your pocket.
This number removes emotion from negotiations. When that offer comes in at $615,000, you know exactly what it means. You need an extra $6,000 to make this move work. You can negotiate higher, accept and fund the gap, or walk away.
Should I Buy First or Sell First in Calgary's Market?
Your walkaway number helps determine your strategy:
- If your walkaway number is close to or above current market value, sell first. There's no margin for error.
- If your walkaway number is well below market value, you have the luxury to buy first because you have a financial cushion.
This isn't about feelings or market predictions. This is math. If homes like yours are selling for $670,000-$680,000 but you only need $621,000 to make your move work, you have $50,000-$60,000 in cushion. That changes your entire approach.
